In a short video and an extensive data site, Google Zeitgeist takes us back... and shames us with what we have searched for in 2011. This year we searched Google for answers about Rebecca Black, Steve Jobs, Google+, and the nonexistent iPhone 5.

The reaction: Holy cow, "if this is the spirit of our time, then we are living in a sad time," says Sam Biddle at Gizmodo. What we apparently think "mattered" doesn't get any better if you dig through Zeitgeist a little deeper: Planking? "Tom Brady Haircut"? Google is showing us that we're, collectively, "awful people." Hey, "it was a weird year," says Jon Mitchell in ReadWriteWeb. Yes, the Arab Spring, the death of Osama bin Laden, and lots of other weighty things are more important than Adele, but with so many "grim and tumultuous events" in 2011, maybe we can be excused for our "mostly frivolous" googling. I'm in the "shame on humanity" camp, says Nitasha Tiku in BetaBeat. But Google's video retrospective is "actually quite moving," if you can ignore "the hideous Coldplay soundtrack — and that thing about Rebecca Black." Watch the video here...
